well we replaced the radiator with one that jeff (boostlee) had. its practicaly brand new. and it still had the same problems..and we have pretty well come to the conclusion that it is the radiator cap that is bad and letting all the pressure out. in the morning im going to run to the auto parts...

Ok, one other thing i forgot to mention. The car is pushing some coolant out of the over flow tank, but not much. As for the radiator cap, it is a Greddy 1.3 bar that i borrowed off Boostlee, and it is less than 2 years old. However, when i poped the hood after driving the car i heard air...

the car has been compression tested and a block tester was done by the toyota dealership. both test were good... only thing i can think of is if its leaking under a load while driving and not just while sitting at idle. if it was doing that then i wouldnt see the leak.. i'll try your suggestions...

so as some of you know recently my ct60-1 turbo took a dump, the car was losing coolant, and over heating. I bought a Lipp Boss turbo which iam EXTREMLY impressed by.. well i got the car running and everything seemed great untill the spark plugs started sputtering and missing under a heavy load...

you wana bet the turbo will cause it to over heat?? it caused my car to over heat cause it was burning coolant and leaking some coolant. just replaced the turbo and the car runs fine now.

a ct-26 pushing 500hp?

that really helped, thanks!

ya i got the whole kit with lines, but its used so it didn't come with instructions,, but thanks!

im kinda having the same problem, my car was over heating and coolant was being pushed out the overflow tank, i took my car to a shop had it compression tested they were all between 145-160, then they did a block tester and there were no exhaust gases in the coolant, so that was good. the shop...

i just got a aeromotive fuel pressure regulator for my car, and i was just wondering if anyone had instructions for the install? or if you could simply explain it to me, thanks!

ya you just have some air in there,.. doesnt mean you have bhg.. just try burping the car and see what happens before you compression test it.

spark plugs?

ok. so what is the point of running an aftermarket fuel pressure regulator if you have it set at stock setting? sorry if thats a stupid question..lol

i thought you wanted the fuel pressure to be in the 40s?

ok thanks for that page. that gives me an idea.. but what kind of fuel pressure are some you guys out there using? with 550s and all the other supporting mods?

i just bought a aeromotive fuel pressure regulator, i have the lex afm and 550cc injectors, i also have a wideband and safc. i was just wondering as to how much pressure i should have the regulator set to? thanks

i had the same problem when the coupler poped off my turbo! sounds like boost leak

my car has the same problem.. i have almost the same mods, i have lex and rc 550s and all the other mods.. my car idles at like 17+ afr and thats with the safc turned up to like +11 for just idle

now that sounds awsome!

wow i just read the whole thread car has come a long way.. when is that single turbo going that you were talking about getting?
